The first step in solving the equation 3x+4=20 is to from each side. this is an example of the property of

3x+ 4 = 20

First you SUBTRACT 4 from both sides . Since these are inequalities we do reverse PEMDAS (Parentheses , Exponents , Multiply , Divide , Add ,Subtract). Then you will have an equivalent equation of

3x=16

Now we have to isolate X . So we divide 3 by both sides . Which will get 5.3333...

Therefore , The answer will be

The first step in solving the equation is to SUBTRACT from each side . This is an example of the subtraction property of EQUALITY

Subtract 4 ,

Subtraction property of equality

Step-by-step explanation:

When we solve a one variable equation then we isolate the variable in the left side,

Here, the given equation,

3x + 4 = 20,

For isolating x on left side first we need to remove constant term in the left side,

For this we need to subtract 4 from each side,

That is, 3x = 20 - 4

∵ Subtraction property of equality states that an equation does not change when we subtract same number from each side of the equation.

i.e. a = b ⇒ a - c = b - c, Where, a, b and c are real numbers.
